Khloe Kardashian had one-night stand after MTV VMAs

Khloe Kardashian has confessed she had a one-night stand after the MTV Video Music Awards in 2007 - with a secret celebrity.

The 31-year-old beauty enjoyed a night of passion with the unnamed famous man following the star-studded bash in Sydney, Australia.

She was happy to leave it as a one/off liaison but the guy was keen to continue their romance.

Speaking to her friend Malika Haqq in a video diary posted on her website, she said: "I had a one-night stand with someone in Australia, just one.

"But remember, then he came to the States and wanted to date me again? I never saw him again and I was like, 'Uh, no, you're not supposed to come here!' "

Khloe - who married her estranged husband Lamar Odom in 2009 - had to repeatedly repel the man's advances as he wouldn't leave her alone online.

She said: "I met a guy who was performing at the MTV Awards, hooked up with him here and left.

"He had to leave town and we both didn't live here, we all came here for the awards.

"I went back to [Los Angeles], and all of a sudden he's calling me, IMing me, instant messaging me on AOL - back in the day - he was like, 'I finally came out to L.A., I want to have a relationship with you.'

"And I was like, 'Malika, is this normal?!' It was just to do something in Australia."

However, Khloe admitted she enjoyed their encounter, even though it was only brief.

She said: "I had the coolest room, and it had a bath - like the whole room was huge and had a bath in the middle of the room.

"And I was so confident, I took a bath in front of him, I don't know what was happening!"
